Observations

-22,000 g/mol PVOH did not form a hydrogel. After three freeze thaw cycles (24 hours @ -20°C, 24 hours at room temperature) the sample was still very much a liquid. This being said, we have concluded this molecular weight is not suitable for our drug delivery system.

-nanospheres that were prepared on Wednesday may be too small for our system. We are looking to alter the procedure slightly so we can make spheres slight bigger (micro or even milli scale)
